Tibet Warming At Twice Global Average

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


The Tibetan plateau is heating up by 0.3°C each decade. At more than twice the worldwide average, according to a new study from the Tibet Meteorological Bureau, as reported by New Scientist. The research reinforces a growing realization that high altitudes in tropical regions are experiencing dramatic temperature increases similar to those at the poles. Over the last 50 years, temperatures in the Arctic and Antarctica have risen by 0.2°C and approximately 0.5°C per decade, respectively, according to data from the Intergovernmental Panel on Climate Change. The reason surface temperatures at the poles are warming so quickly is because the seawater temperature around them has risen faster there than anywhere else on Earth. Warming waters also play a role in the tropics. When the already warm tropical waters heat up further, due to global warming, they evaporate even more moisture, which rises straight to the upper atmosphere.

In 2000, researchers published a study looking at temperature changes on the Tibetan plateau since the 1950s, which found that temperature was not only increasing with time, but also with elevation across the plateau. They concluded the plateau is one of the most sensitive areas in the world in its response to global climate change. A study published in 2006 in Science found similar increases in air temperature at high-elevation weather stations in the Andes.

The Tibetan Plateau is also one of John Schellnhuber’s tipping points, reported on in Mother Jones “The Thirteenth Tipping Point.” Check out what happens when it tips. JULIA WHITTY

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
